WINDING-ROLLER FOR Looms, 800.

- SPECIFICATION forming part of Letters Patent No. 245,138, dated August2, 1881.

Application filed March 15, 1881. (N0 model.)

To atlwhom it may concern:

Be it known that I, JOHN UONNELLY, of Hallowell, in the county ofKennebec and State of Maine, have invented a new Improvement inWinding-R0llers for Looms, &c., of

which the following is a full, clear, and exact a longitudinal sectionof a winding-roller of my invention." Fig. 2 is an end view of the same.Fig. 3 is a cross-section of the roll as expanded, and Fig. 4 is across-section of the roll in acollapsed condition. y

Similar letters of reference indicate corresponding parts.

The cylindrical body of the roller, as shown, is formed bythreesegments, aa a; but there may be four or more. The segments a are turneddown or formed with rabbets at their ends,

upon which caps bl) are held by screws 0, that enter the ends of thesegments through radial slots d, that are formed in theends of the caps.The screws 0 may thus slide in the slots as the segments are moved inand out, and the internal diameter of the caps should be such that theends of the segments will he held tightly when expanded by the deviceshereinafter described.

Within the caps b the end of the segments are grooved to receive elasticrings 0, that tend to close the segments inward.

Through the center of the roll passes a shaft or spindle, f, by whichthe roll is supported and turned. This shaft is squared where it whileit is expanded.

passes through the ends of caps b, so as to carry-the roll, and isfitted within the roll with collars g 9, that are formed with beveledends. The segments a are provided with lugs or projections h, thatproject inward from theinner surfaces of the'segments. There are twolugs, h, on each segment adjacent to the two collars g, so that whensuch lugs rest upon the plain surface of the collars the segments areheld outward. v The shaftfcan be moved endwise to the extent allowed bythe fixed collars i on the shaft, outside caps b, so as to remove thecollars g from between the lugs h, and thesegments are then frec'tocollapse.

In use the material is wound on the roller To remove the material fromthe roller, shaft f is to be moved endwise to release the segments,which then collapse, and the diameter of the roller is reduced to anextent that allows ready removal of the roll. By moving the shaft in theopposite direction the beveled ends of collars 9 act against pins h andforce the segments outward.

Having'thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is'

1. The collapsible winding-roller consisting of segments a, providedwith internal lugs, 71-, end caps or plates, b, and the shaftf, fittedfor endwise movement in the caps, and provided with beveled collars g,combined for operation substantially as shown and described.

2. ln collapsible rollers, the combination of segments a, provided withlugs h, elastic rings 0, slotted caps b, screws 0, and shaft 1'',provided with beveled collar g, substantially as shown and described,for operation as set forth.

JOHN CONNELLY.
